Achuthanandan has served many positions in his long political career. He was the Kerala State Secretary of the CPI(M) between 1980 and 1992 and he became a member of the Politburo in 1985. He has also been active in parliamentary politics; he was elected as a member of Kerala Legislative Assembly in 1967, 1970, 1991, 2001, 2006, 2011 and 2016. He was the Leader of Opposition in the Kerala Legislative Assembly from 1992 to 1996, from 2001 to 2006 and from 2011 to 2016. He was the editor of CPI(M) mouth piece in Malayalam, Deshabhimani daily. He was the Chief Ministerial candidate for 1996 State elections. In those elections, LDF gained 80 out of 140 seats, but Achuthanandan, who contested from Mararikulam in Alappuzha district, lost by a margin of 1965 votes. Thus, E.K. Nayanar, who held the position twice earlier, became Chief Minister again.

He entered politics through trade union activities and joined State Congress in 1938. In 1940, he became a member of the Communist Party of India (CPI). During his 40 years as a politician he was imprisoned for five years and six months and was in hiding for four and half years. He was a state secretariat member of the CPI in 1957.[14] He is the only living Keralite among the 32 members who left the CPI National Council in 1964 to form the CPI(M). He was Secretary of the Kerala State Committee between 1980 and 1992. Since 1985 he is the member of the CPI(M) Polit Bureau until he was removed as a party disciplinary action. He is the senior most leader of CPI(M) in India.

After four consequent electoral defeats, Parakala withdrew from the electoral arena. He concentrated on public discourse through the current affairs programmes on television and his profession as a policy analyst. But in 2008 some like minded people approached Parakala with an intention to start a new alternative political platform. Popular matinee idol Chiramjivi was to be the face of the party. Parakala lent his support to the idea and worked to establish the party. He was one of the signatories to the application for the registration of the Political Party 'Prajarajyam' and one of its founding General Secretaries and spokespersons. But the experimented turned out to be another disappointment for Parakala. He found that there was no clear agenda and party tickets were given in exchange of money. Several local leaders openly hurled accusations at the party leadership. Parakala held a press conference at the party headquarters and launched a scathing attack on the party leadership for betraying the ideals for which the new platform was to stand for. Terming the party as Poisonous Ivy (Vishavruksham), he announced his resignation. That address to the press was telecast live and thousands viewed it across the state. That spelt the doom for the party. A party that was hoping to have an impressive performance ended up with securing just 18 seats with the charismatic Chiramjivi himself losing one of the two seats he contested from his native place. Many people still question the moral and ethical basis of Parakala holding a press conference at the party headquarters to criticise the party and its leadership. Opinion is still bitterly divided on this. The Prajarajyam seems to have put an end to the party and electoral political career of Parakala.
